FIG. 1 is a sectional view of a camera device provided in a preferred embodiment of the present disclosure.

FIG. 2 is an explored view of a part of elements of the camera device shown in FIG. 1.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

A clear and complete description of technical schemes of embodiments of the present disclosure is provided below with reference to the accompanying drawings.

FIG. 1 and FIG. 2 show a terminal provided in a preferred embodiment of the present disclosure. The terminal can be implemented by a cell phone, a personal digital assistant (PDA), or a tablet computer. The terminal includes a camera lens 200 and a camera device 100. The camera lens 200 is mounted on the camera device 100. The camera device 100 includes a housing 1, a mounting barrel 2 for mounting the camera lens 200, a supporting member 3, elastic members 4, a rotating ring 5, and a driving motor 6. The camera lens 200 is fastened in the mounting barrel 2. The housing 1 and the supporting member 3 are fastened and connected to each other. All of the mounting barrel 2, the rotating ring 5, and the elastic members 4 are deployed inside the housing 1. The driving motor 6 is fastened to the supporting member 3. In such a manner, the entire camera device 100 becomes a single module for ease of assembling and disassembling.

One end of the housing 1 is fastened to the supporting member 3 and the other end of the housing 1 has a protrusive limiter 11 disposed on an inner wall thereof. The use of the protrusive limiter 11 can make the mounting barrel 2, the rotating ring 5, and other elements confined in the housing 1. The mounting barrel 2 is positioned circumferentially with respect to the housing 1 such that the mounting barrel 2 is only able to be directed in a slantwise position without rotation with respect to the housing 1. The mounting barrel 2 has a ring-shaped flange 21 disposed on an exterior peripheral face thereof. The ring-shaped flange 21 and the mounting barrel 2 are coaxially aligned to each other. The central axes of the mounting barrel 2 and the rotating ring 5 form an angle such that the mounting barrel 2 is inclined with respect to the rotating ring 5.

There are a plurality of elastic members 4 arranged around the ring-shaped flange 21. The elastic members 4 are disposed between the ring-shaped flange 21 and the protrusive limiter 11 for providing a force to make the ring-shaped flange 21 and the protrusive limiter 11 away from each other. The rotating ring 5 is disposed between the ring-shaped flange 21 and the supporting member 3. The rotating ring 5 is connected to the supporting member 3 but is able to rotate about its own axis. The driving motor 6 is connected to the rotating ring 5 in a transmission way for driving the rotating ring 5 to make it rotate. The rotating ring 5 has a protruding member 51 disposed thereon and the protruding member 51 is rotated along with the rotating ring 5. The protruding member 51 is abutted on the ring-shaped flange 21, and the elastic member 4 located relative to the protruding member 51 is pressed. The elastic member 4 located at the other side with respect to the axis of the ring-shaped flange 21 can provide an elastic force such that the distance between the ring-shaped flange 21 and the protrusive limiter 11 is relatively large at this place. Therefore, cooperation between the elastic member 4 and the protruding member 51 can make the mounting barrel 2 maintain at a tilted state.

When the protruding member 51 rotates along with the rotating ring 5, the protruding member 51 can abut sequentially on different peripheral positions of the ring-shaped flange 21. In such a manner, the mounting barrel 2 can be sequentially tilted toward different directions. The camera lens 200 is placed in the mounting barrel 2 and they are coaxially aligned. Following the lead of the mounting barrel 2, the camera lens 200 can be tilted toward different directions such that a relatively large view angle is acquired and a wide-angle effect is carried out. A plurality of images of different view angles may be obtained when the camera lens 200 is tilted toward different directions. By a synthesis of the images carried out from multiple directions, a picture of a large view angle is thus obtained. Therefore, a camera lens of an ordinary view angle in the existing market is sufficient to carry out the wide-angle effect.

Both of the ring-shaped flange 21 and the rotating ring 5 are disposed outside the mounting barrel 2. This can reduce axial dimension of the mounting barrel 2 and is beneficial to miniaturization of the terminal device. Since the change to the mounting barrel 2 is the tilt angle and the mounting barrel 2 does not require to be rotated, the camera lens 200 does not need to rotate. Therefore, it is convenient to carry out electrical connection between the camera lens 200 and a system board and this facilitates the transmission of image data.

In the present embodiment, the elastic members 4 are elastic sheets. Their structures are simple and are easy to be processed and prepared. The camera device 100 further includes a connecting ring 40 in a form of a circular sheet. The connecting ring 40 and the plural elastic members 4 are integrally formed. The connecting ring 40 is connected to the protrusive limiter 11. One end of each of the elastic members 4 is fastened to the connecting ring 40 and the other end of the elastic members 4 is abutted on the ring-shaped flange 21. The connecting ring 40 can connect the plural elastic members 4 to become a unity. Therefore, it is convenient to process and prepare the plural elastic members 4 and facilitate the assembly.

During preparation of the elastic members 4, a metal material in a form of a sheet can be punched to form the connecting ring 40 and the plural elastic members 4. This process is simple and convenient, and the cost is low. During the assembling process, it is only required to put the unity of the connecting ring 40 and the plural elastic members 4 upon the mounting barrel 2. There is no need to use a fastening member to fasten the connecting ring 40 to the ring-shaped flange 21 or the protrusive limiter 11.

In other embodiments, the elastic members 4 can be deployed between the ring-shaped flange 21 and the protrusive limiter 11. One end of each of the elastic members 4 can be directly fastened to the ring-shaped flange 21 (or the protrusive limiter 11) while the other end is abutted on the protrusive limiter 11 (or the ring-shaped flange 21). In another further embodiment, the elastic members 4 can also be implemented by compressed springs. The two ends of the compressed springs can be respectively abutted on the ring-shaped flange 21 and the protrusive limiter 11 for providing a force to make the two elements away from each other. In such a manner, the mounting barrel 2 is maintained at a tilted state. Alternatively, the elastic members 4 can also be any other elements capable of providing an elastic force.

The protruding member 51 is a ball. The rotating ring 5 has a locating slot 50 disposed thereon for confining the ball. The locating slot 50 can make the rotating ring 5 drive the protruding member 51 such that the protruding member 51 rotates together with the rotating ring 5 about the axis of the rotating ring 5. In the case that the protruding member 51 is implemented by a ball, the friction between the protruding member 51 and the ring-shaped flange 21 can be reduced and this facilitates the rotation of the protruding member 51. In other embodiments, the protruding member 51 can also be implemented by a bump or a boss fastened to the rotating ring 5. The surface of the bump or the boss can be a spherical surface in order to facilitate cooperation with the ring-shaped flange 21. The rotating ring 5 can be integrally formed with the bump or the boss for facilitating its fabrication.

The driving motor 6 is connected to the rotating ring 5 via a transmission gear set 61. By using the transmission gear set 61, the stability of rotation of the rotating ring 5 can be assured and the rotation speed of an output shaft of the driving motor 6 can be transformed into an appropriate rotation speed of the rotating ring 5. The rotating ring 5 may be sheathed with a gear in order to connect to the transmission gear set 61. The driving motor 6 is disposed outside the housing 1 so as to reduce the size of the housing 1 and facilitate the installation of the driving motor 6. The driving motor 6 and the transmission gear set 61 can be combined to form an integrated structure. That is, the driving motor 6 and the transmission gear set 61 are integrated into a single module for facilitating the assembling, disassembling, and maintenance.

One end of the mounting barrel 2 near the protrusive limiter 11 is extending out of the housing 1. This can prevent the protrusive limiter 11 from interfering the view angle of the camera lens 200 after installation of the camera lens 200. In an embodiment, the axial dimension of the housing 1 is decreased such that one end of the mounting barrel 2 can be located outside the housing 1.

In order to carry out circumferential positioning between the mounting barrel 2 and the housing 1, a circumferential positioning structure can be disposed between the two elements. For instance, the ring-shaped flange 21 has a positioning protrusion disposed thereon and the housing 1 has a positioning slot disposed on an inner part thereof. The positioning slot is a strip disposed along an axial direction of the housing 1. The positioning protrusion slides within the positioning slot. The cooperation of the positioning slot and the positioning protrusion can make a point on the ring-shaped flange 21 corresponding to the position of the positioning protrusion move along the axial direction so as to carry out altering the tilt angle without causing rotation of the ring-shaped flange 21 with respect to the housing 1. Alternatively, the positioning protrusion is arranged on the inner wall of the housing 1 and the positioning slot is arranged on the peripheral surface of the ring-shaped flange 21. In another further embodiment, a slot can be disposed on the ring-shaped flange 21 at a position abutted on the elastic member 4. The elastic member 4 is abutted on the slot. By the interaction between the elastic member 4 and the slot, the mounting barrel 2 can be positioned circumferentially with respect to the housing 1 so as to prevent the rotating ring 5 from causing the mounting barrel 2 to rotate.

The mounting barrel 2 has an elastic metal piece 22 disposed therein for connecting to the camera lens 200. The elastic metal piece 22 is used to abut on a metal joint of the camera lens 200 so as to carry out electric connection with the camera lens 200. Once the camera lens 200 is mounted on the mounting barrel 2, the camera lens 200 is fixed and electrically connected. Further, there is a flexible circuit board 23 disposed outside the mounting barrel 2. One end of the flexible circuit board 23 is electrically connected to the elastic metal piece 22 and the other end can be connected to a system board of the terminal. In such a manner, the connection between the camera lens 200 and the system board is carried out. By use of flexibility of the flexible circuit board 23, the flexible circuit board 23 may be tilted and deformed to a certain degree along with the mounting barrel 2 but the electrical connection is not affected. The other end of the flexible circuit board 23 can be plugged on the system board or detachably connected to the system board via an electrical connection member so as to facilitate assembly and connection between the camera device 100 and the system board. It is convenient to assemble and disassemble the camera device 100.

In the camera device 100 provided in the present disclosure, an existing camera lens 200 in the market can be mounted on the terminal device. The camera lens 200 is mounted on the mounting barrel 2. When a photo is being taken, the driving motor 6 drives the rotation of the rotating ring 5, and the mounting barrel 2 and the camera lens 200 can be sequentially inclined toward different directions by the cooperation of the protruding member 51 and the elastic members 4. In such a manner, images of various view angles are obtained so as to carry out the effect of wide angle. The obtained images of various view angles can be synthesized to carry out a wide-angle picture by post processing with use of software in the terminal. The camera device 100 is simple in structure and is easy to be fabricated without occupying much inner space of the terminal.
